INSULATED COMPROMISE RAIL-JOINT.

Specification of Letters Patent.

Patented Jan. 28, 190s.

To all whom it may concern:

Be it known that I, BENJAMIN WQLHAUP- TER a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and'useful Improvements in Insulated Compromise Rail-Joints, of which the following is a specification.

This invention relates to that class of insulated rail joints embodying a two-part or sectional supporting base for the rail ends, whereby a separate supporting base section is provided for each rail end, while at the same time providing for such insulation of the joint that there is no insulating material which is required to carry the load or weight of the assing trains.

To t is end the' invention primarily contemplates a simple, thoroughly practical, and strong construction of compromise rail joint having a two-part orsectional supporting base wherein each of the opposite joint bars or shoes is provided with a short length integral base section for one rail end, each of said base sections'being adapted to afford the rail end thereon a support on both sides of the meeting point of the rail ends.

A more general object ofthe invention is to improve rail joints of the compromise or step type which-are employed to connect rails of different heights and sections, so that the tops and inner sides of these dissimilar rails are supportedin alinement. In this connection,

the invention has in view the provision of a separate or individual supporting base or base section for-each rail end whereby the individual support for each rail end is in a sense independent of that for the other, and thus admitting of the very desirable feature of providing means whereby the supporting base for one of the dissimilar rails, in a compromise rail joint, afiords said rail end the support of the ties on both sides of the meeting point of the rails without metallic contact with the corresponding base section.

Furthermore, the invention also provides a construction of compromise rail joint where- ,in the joint may be thoroughly and efiect- 'ively insulated throughout with a minimum 50 amount of insulating material, and without disposing any insulating material in places where the same would receive the load or weight imposed on the rails.

With these and many other obj ects in view, which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

- The invention is exemplified by the practical embodiments thereof shown in the accompanying drawings, in which:

Figure 1 is a sectional perspective view of a compromise rail joint constructed in accordance with the present invention. Fig. 2 is'a central longitudinal sectional view thereof showing more clearly the differential height or stepped relation of the separate base sections- Fig. 3 is a vertical cross sectional view on the line 33 of Fig. 2. Figs. 4 and5 are separated perspective views, respectively, of the opposite joint shoes employed in the construction of joint shown in the receding figures Fig. 6 1s a side elevation of an angle bar type of step joint embodying the present invention. Fig. 7 is a bottom plan view of the joint shown in Fig. 6. Fig. 8 is a cross sectional view of the joint on the line 88 of Fig. 6. Fig. 9 is across sectional view on the line 99 of Fig. 6.

Like references designate corresponding parts in the several figures of the drawings.

The essential features of the invention may be embodied in various forms of construction accordin to the special conditions to be met, but for ilustrative purposes there is shown in the drawings one of thapreferred and practical embodiments of the invention. This design of compromise rail joint, shown in the drawings, embodies in its organiza tion the dissimilar service rails 1 and 2 of different height and section, the oppositely arranged complemental joint shoes 3 and 4, the wooden or equivalent filler blocks 5 interposed between the upright members of the shoes and the sides of the rails, and the series of joint bolts 6 passing'throughthe alined bolt holes or openings in the rails, the filler blocks, and the said upright members of the shoes. The joint shoes 3 and 4 are located respectively at opposite sides ofthe dissimilar rails L and 2, and each consists of anangle' or angle plate having an upright member 6 constituting a side jointbar for the joint, and a short length horizontal base section 7 preferably formed integral with and projected inwardly from the lower edge indicated in the preferable construotion of oint, the upright member or joint bar 6 of v each shoe is integral with each base section or base plate 7, and at the outer corner of the.

shoe the same mayalso be provided. with a continuous reinforcing and spiking flan e 8' length approximately equaling one-half the. full length of the rail joint members so that. each base section receives and supports thereon one rail end. In this connection it will be observed that the opposite joint shoes 3 and 4 are arranged inrights and lefts, and

are so constructed that one of the shoes,. designated by the numeral 3, has its base section '7 projected inwardly from one end portion thereof only, while the opposite shoe, designated by the numeral 4, has its base section 7 projected inwardly fromthe correspondinglv, but diagonally, op osite end portion of the same. Hence, eac base section receives thereon one rail end to afford the'latter asupport on both-sides of the meeting point of the rail ends without con-- tact with the; cones onding base section or su porting base for t e other rail end.

n this desim of joint, one of the distinctive features thereof resides in the fact that- 'in order to secure the compromise or stepping effect necessary to connect the; dissimilarrails so that the to s and inner sides thereof are supported in a ement, it is only necessary to have the separate base sections 7 of the oppositeshoes 3 and 4 in a stepped re-' lation, that is, of different heights so that while each of the dissimilar rails has a-similar kind of support, the tops or running surfaces thereof are held in alinementl of joint illustrated in the drawings, the stepped relation of the separate base section 7, or the differential height thereof, is preferably rovided for by making one base section thicker than the other, thereby disposmg the upper rest or supporting. faces in di erent e eva-tions, that is, in different horizontal planes, as plainly shown inFigs. 2 and 3 of'the drawings.

' In the construction described, it will be observed that by reason of interposing the wooden or equivalent filler blocks 5 between the upright members or side bars 6 of the shoes and the rail sides, the exterior design and dimensions of the conventional 'oint shoe or shoe angle may be preserved. .T -at is, the

I said upright. members or side bars of the shoes may be left of uniform desi throughout without regard to the dissini in the In the form side joint bars amen section of the connected rails 1' and 2,- thus permitting the stepping of the'rails being ac com' lished solely through. the differential. heig ts of the two base-sections-7 7, and the recessing of the filler blocks along their inner sides at one end portion thereof as indi cated, at 9 in Fig.v 3, to compensate for the projection of the'larger rail beyond the planeof the sides of the smaller rail.v Also, by

reason of the e'mployment'of'the. wooden or.

equivalent filler blocks 5, a well defined air w or interval ismaintained betweenthe and longitudinal edgeof each base section 7 the opposite joint shoe, and insulation may or may not be employed at this point to pro- :vide for insulating .each shoe from the longitudinaledge of thebase section carried by the otherishoe, while in order to provide insu lation'between the rail ends andalso between the inner adj acent end edges of the base sections, an insulating end post 10 may be utilized to perform these functions. The insu lating. end post 10. is of the conventional design, the same being adapted for interposi-v tion between the rail-ends, but the present in vention contemplates providing the end post 10'with a base extension 11 ofsuflicient ex tent to project into and close the space between the inner end. edges of the base sections To complete the insulation of the joint, any suitable approved insulating expedients may be employed-for insulating thejoint bolt 6, such for instance as the insulating washer and bushings 12 arran'ged at the inner sides of the heads and nuts of the bolts and lining the bolt holes in the upright member's-or bars 6 of the separate shoes.

, As already indicated, the essential features of this invention may be embodied in various forms of construction,according to the spe- 1 cial conditions to be met, and therefore the design of side joint bars- 6 may be varied with-- out departing from or sacrificing any of the advantages of the invention. For illustrative purposes, the side joint-bars 6 are shown in the drawings as constituting the upright members of shoe angles cooperating with filler blocks interposed between the said members and the sides of the rails, but obviously as shown in Figs. '6 to 9 inclusive, the said designated in said figures by may be made of the angle the number 15, I

fitting the sides of the rails bar type closely with suitable insulation 16 interposed, without altering the feature of having each of said side joint bars provided with a short length base section 7 affording a support for one rail end, and the separate base sections 7 being disconnected and'having their support ing surfaces arranged in stepped relation.

Other obvious modificationsof the invention will readily suggest themselves to those skilled in'the art, and

understood that various changes in the form,

it will therefore be vantages o proportion,- and minor details of constructidn may be resorted to without departing from the s irit or sacrificing any of the ad-' the invention. I'claim; a
